My local camera store explained to me that Hoya has two lines, but as I recall it may not be immediately apparent from the names which is which. Anyway one is cheap , the other is higher quality and they said equal to the B+W and Heliopan etc. Someone earlier on this thread called them the "Pro " filters I think.
I bought the slim B+W UV haze mrc 82mm filter from bhphotovideo. I did not take my hvx camera out of the box until the filter came in. I am currently waiting for the B+W slim polarizer filter to be in stock, that sucker is $$ but I REFUSE to buy anything else but B+W, for me, if it's in front of the lens, it has to be B+W or it's just not good enough for my camera.
You can cut corners with other production gear, I just would advise against cutting corners in front of the lens.
